@arthurgur: Any update on this PR? This would be a great enhancement.

Agree, this would be very useful.

This will be unblocked once https://github.com/hashicorp/terraform-provider-kubernetes/pull/2561 is merged.

@mdering This is still marked as blocked due to being a v1.29 K8s feature. We currently only support features up v1.28. We intend to do a k8s version bump in the next major release. The milestone can be seen here: https://github.com/hashicorp/terraform-provider-kubernetes/milestone/11
